The bassline in this song is very simple and goes on throughout most of the song. If you don't have a bass guitar, you can use a keyboard at your preferred patch/sound setting instead since the original song uses a synthesizer as the bassline, just using the D-C-B-Bb-F-G notes in that pattern and hitting the D note for 2 bars in the intro and one bar in the outro. It is actually very easy to simulate on most standard synthesizers or keyboards.
